Abstract

496,284. Sparking - plugs. GRAF, L. Feb. 23, 1937, No. 5479. Void. Convention date, Feb. 17. [Class 7 (iv)] Cavities 2a, 9a are formed in the adjacent ends of one or both electrodes. The earthed-electrode end may be spherical or cupped. Ribs 24 are formed on the in sulator adjacent tc openings 25 in the casing. The ring or collar 23 acting as a spacing member be tween the central electrode and the bore ir the insulator is made from material of low thermal conductivity A washer 13 of asbestos separates the cupped upper surface of the electrode collar 4 from the end of the insulator. Spring washers 11 within a cap 10 permit relative movement, due to thermal expansion, between the insulator and electrode.
